LOOM-SHUTTLE.

Application filed June 17, 1913.

To all whom it may concern:

Be it known that I, PATRICK F. HIGGINS, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to improvements in loom-shuttles of the type designated as self-threading, and the object is to provide an improved shuttle of this character which may be quickly threaded and from which the thread will be positively prevented from escape during the operation of the shuttle.

With the above object in view, the invention consists in the novel features of construction hereinafter fully described, particularly pointed out in the claims, and clearly illustrated by the accompanying drawing, in which- 7 Figure 1 is a top-plan view of the threaddelivering end of a shuttle constructed in accordance with my invention; Fig. 2, a side view of the same Fig. 3, a transverse sectional view taken on the line A-B of Fig. 1; Fig. 4:, a side-elevation of the eyemember of the shuttle, and Fig. 5, a bottom plan view.

I am aware that many different forms of shuttles of the type to which the present invention relates have heretofore been provided. Those in general use however, have a serious defect, namely, of permitting the escape of the thread and consequent unthreading of the shuttle. When the shuttle is in motion that portion of the thread between the bobbin and the eye has a tendency to what may be designated as buckle and lift, and following the same steps or course by which it was threaded into the eye, disengage itself therefrom.

It is the purpose of my invention to so form and locate the eye that such unthreading is impossible.

The shuttle I have illustrated is a right hand one, but the invention is equally applicable to a left-hand shuttle.

Referring now more particularly to the drawing, the numeral 1 designates the shuttle-body which is of the ordinary form. At the front-end thereof is a central recess 2, from one side-wall of which extends the curved threading-slot 3 which is disposed downwardly from the top-surface of the shuttle-body and connects with a slot 4 Specification of Letters Patent.

formed in the side of the body and extend ing rearwardly to a transverse opening 5 located just in front of and in part below the bottom-wall 6 of the recess 2. Inserted and secured by a pin or other suitable means in said opening 5, is the eye-member illustrated in detail in Figs. 4 and 5 of the drawing. The eye-member is shown in the form of a metal sleeve 7 having a diagonal thread-inlet slot 8 extending longitudinally thereof from its outer end at a point below its center to its inner end at a point above its center where the metal is cut-away so that thesleeve at that end has its upper portion projecting beyond its lower portion as at 9, and the lower edge of the projecting portion is a continuation of the upper wall of the slot. This lower edge of the projectingfportion 9 curves into the front-edge 10 of the latter, and the front-edge 10 continues into the lower edge 11 of said projecting-portion on the opposite or eye-side of the sleeve. The eye 12 is formed in this side of the projecting portion and has an opening 13 at its bottom-side to permit ingross of the thread, and the lower-edge 11 of the projecting-portion of the sleeve curves downwardly and rearwardly to this ingress 13, forming a curved shoulder. When in position in the shuttle-body, the ingress 13 to the eye 12 is located slightly below the bottom-wall 6 of the recess 2, and the opening 5 in which the sleeve is placed is somewhat larger in diameter than the sleeve so that there is sufficient space for the thread to pass around the forward portion thereof from the slot 4 in order to enter the threadinlet slot 8 of the eye-member.

In operation, the thread is inserted in the slot 3, from which it passes into the slot 4, and then around the forward side of the sleeve to the lowermost end of the threadinlet slot 8. Entering this slot 8, it passes along the upper wall thereof and the lower edge of the projecting-portion 9 to and around the front-edge 10 of the latter and then down along the curved edge or shoulder 11 on the opposite side of the projecting-portion and the bottom-wall 6 of the recess 2 to the ingress-opening 13 where it enters the eye 12.

From the above description, it will be seen that by reason of the shape of the eye and the curved edge or shoulder 11 as well as the location of the eye with respect to the wall 6 of the recess 2, and the location and disposition or the thread-inseam 8,1 the thread to disengage it is impossible for the eye either by buckling or otherwise, and at the same time the shuttle is quickly and readily threaded.

Having thus fully described my invention what I claim as new and desire to secure by "thread-inlet said shuttle horizontal, connecting threading-slots com- United States, is

A loom shuttle having a tubular eye-- memberplaced transversely in the deliveryend thereof, said eye-member having in its c aside-wall next the bobbin an eye open at its a, bottom, and a thread-inlet slot in its opposite side-wall inclined upward from the outer end of the eye-member, and a downconducting the wardly curved shoulder for thread from the slotto the opening of the eye, said shuttle being formed with vertical ,and horizontal connecting threading -slots the eye-member.

A loom-shuttle'having an eye-member placed transversely in the delivery-end thereof, said eye-member formed with an eye openat its bottom, in combination with Copies of this patent may be obtained for five cents each, by addressing the edge of the projecting a recess formed in the shuttle-body at the delivery-end thereof having its bottom-wall above the openings to the eye, and threading-slots for leading the thread to said eye.

5. A loom-shuttle having a tubular eyemember placed transversely in the deliveryend thereof, said eye-member being cut away at its inner end to form a projectingportion extending from its upper side, an eye formed in the projecting-portion in the side next the bobbin having an opening at its bottom, a thread-inlet slot formed in the eye-member extending upward from its outer end to the upwardly curved under portion on that side of the eye-member, said curved edge con-- tinuing into the end-edge of the projectingportion and the end-edge into the under edge of the projecting-portion on the eye side of the eye-member which latter edge is curved downwardly and rearwardly to the opening of the eye, and vertical and horizontal threading slots in the shuttle-body communicating the eye-member.

6. A loom-shuttle having a tubular eyeinember placed transversely in the deliveryend thereof, said eye-member having an eye in its side-wall next the bobbin, and an inclined thread-slot formed in its opposite side-wall, the portion of the end of the sleeve beneath said eye being cut away with with the thread-inlet slot of open atits bottom formed near one end and curved edges leading from said slot, and the portion of the sleeve forming the lower portion of the eye being curved rearwardly to the opening of the eye, said shuttle being formed with vertical and horizontal connecting threading-slots communicating with t the slot of the eye-member.

In testimonywhereof, I have signed my name to this specification in the presence oi two subscribing witnesses.
